Numerical control equipment

Abstract

Numerical control equipment comprises a main body framework and a workpiece clamping device. The main body framework comprises a base, a first main supporting part and a second main supporting part, as well as a first connecting part and a second connecting part, wherein the first main supporting part and the second main supporting part are arranged on two opposite sides of the base. The first connecting part and the second connecting part are used for connecting two opposite sides of the first main supporting part and the second main supporting part together. The first main supporting part, the first connecting part, the second main supporting part and the second connecting part are connected end to end to form a closed loop structure, and a workpiece exit is arranged at the top of the closed loop structure. More than one of the left side, the right side and the rear side of the main body framework is provided with machining heads and machining head moving mechanisms enabling the machining heads to move along at least three axes. The left side, the right side and the rear side of the main body framework are respectively provided with machining heads, different machining heads can be selected as main machining heads on each lateral side, thus each lateral side of workpieces can be machined with three different power heads under the premises that power heads are not replaced and the workpieces are not clamped for the second time; the machining standard is consistent, the three power heads can work simultaneously, and the efficiency is high.

Description

technical field [0001] The invention relates to numerical control equipment, in particular to a numerical control machine tool. Background technique [0002] Existing numerical control equipment, one is workbench movement. For example, in the invention patent with the application number of 201010284237.9, a CNC gantry vertical compound machine tool is disclosed, including a base, a workbench, and a column. The column is movably connected by a column guide rail or fixedly connected with a composite beam through a fastener. The composite beam passes through the beam. There are more than 2 sliding saddles that are movably connected or fixedly connected by fasteners, and the sliding saddle is movably connected with the main shaft device through the ram guide rail; the base, column, composite beam, and main shaft device are equipped with screw drive devices, and the screw drive The devices are all connected to the electrical numerical control device. [0003] One is the gantry ...

AI Technical Summary

Problems solved by technology

Since the main supporting part is a wall-like structure, when the processing head and the moving mechanism of the processing head are heavy or the processing force of the processing head is large, the main supporting part is easily deformed, causing the main supporting part and the base to be not vertical, so There is a large shape and position tolerance between the processing head and the worktable, resulting in a large shape and position tolerance of the workpiece, which greatly affects the machining accuracy

Since the main support part is a wall-like structure, only one processing head can be installed. When different processing tools are selected to process the workpiece, the processing tool must be replaced, and multiple tools cannot be used to process the workpiece at the same time.
